and in Austria July 26, 1930 14 Claims.

My invention4 relates to hair-curlers having a rotary heated casing and a fixed shield for applying the hair to the casing.

It is an object of my invention to provide a curler in which the hairmayvbe treated by a continuous rotating or rolling motion of the heated casing,-and also by an oscillatoryy rotative motion of the casingabout its axis of rotation.

' To this end I provide means for rotating the casiniT in combination with a control by which the rotary motion vof the casing is changed into oscillatory rotative motion.

Continuous rotation `of the heated casing exerts rolling action on the `hair while its oscillatory rotative motion resembles the action of ironing.

The adaptability of my novel curler is evidently much increased by the two motions it affords. Human hair, but also the hair of furs, may be treated'withY my novel curler, for undulating or curling the hair, or for smoothing curly hair, as

desired.

The normal, readily handled form of the curler is preserved. In lmy novel curler, therefore, just as in a curler Vof the old type, the operator is able to hold the curler freely in any suitable position and to regulate it without Vinterrupting its action.

It is another object of my invention to so design the control for changing the rotary into oscillatory rotative motion that it is operated by the hand holding the curler so that the other hand of the operator is free to arrange the hair.

To thisend I provide a slide for operating the control which is fitted to move on the handle in which the casing is mounted to rotate.

My novel curler islight and therefore does not fatigue the operator, and the operations of hair dressing and treating of furs are performed rapidly, by simple means and in a scientific manner. v

In the drawings affixed to this specification and forming part thereof a hair curler embodying myinvention is illustrated diagrammatically by way of example'.

In the drawings Figl` 1 is an elevation of the complete curler,

Figs. 2 and A3 are partly sectional elevations of the curler, drawn to a larger scale, and showing two distinct positions of its members,

Fig. 4 is an elevation showing the parts of the changing control taken apart,

Fig. 5 is a'section on the lineV--V in Fig. 2,

Fig. 6 is a detail of Fig'. 2, drawn to a larger scale, J Y

Figs. 7, 8 and 9 are sections on the lines VII- VII, VIII-VIII and ITX-IX, respectively, in Fig. 6.

Referring now to the drawings, 1 is the casing, 4 is the handle in which it is mounted to rotate, 2 is a shield having perforations 57 'and adapted to be applied to the casing, 5 is a pivot on the handle about which the shield 2 is fitted to rock, and 3 is a handle on the shield by which it is applied to the casing as shown in Fig. 2.

9 is a exible shaft or cable to which rotation is imparted by any suitable means, preferably by a motor, not shown, and which in turn imparts rotation to the casing 1, in the handle 4. 39 is the slide by which the rotation of the shaft 9 is transmitted to the casing 1 as rotation or as oscillatory rotative motion; 33 is a control sleeve which is operated by the slide 39; 48, 48' are clutching means under the control of the handle 3 for making and breaking the connection of the casing 1 with the shaft 9; 7, 8 are heating wires for conducting current to the casing 1; 22, 22 are heating coils in an insulating core 23 of the casing 1; 17, 18 are brushes in the front end of the handle 4 to which the wires 7 and 8 are connected, and 19, are slip rings on the casing 1 which conduct the current to the heating coils 22, 22.

6 is a cap or support which is placed on the rear end of the handle 4 and receives the exible shaft 9 and the wires 7, 8, and 10 is a spring catch in the cap 6 which engages a groove 11 in the handle 4. 12 and 13 are contact springs on the inner wall of the cap 6 to which the wires 7 and 8 are connected, and 15, 16 are contacting rings on an insulating sleeve 14 which is secured on the end of the handle 4. From the rings 15, 16, wires 7', 8 are taken to the brushes 17 and 18 near the front end of the handle. The slip rings 19 and 20 are held on the casing 1 by insulating rings 21.` By these means the heating coils 22, 22 of the casing are supplied with current during the rotation of the casing.

24 is a bearing, of heat insulating material, in which the front end of the casing 1 is mounted to rotate. The rearward extension of the casing onwhich the slip rings 20 and the insulatingrings 21 are secured is connected with one of the clutch shafts 45 by means of a sleeve 46. 25 is a ball bearing for this clutch shaft and 25 is a ball bearing forthe other clutch shaft 3l. 29 is a shaft extending from a clutch 28,28to the rst unit of the change-control. This shaft, together with the unit, is mounted to rotate in a ball bearing 25", extends through a block 26, and is mounted in a bearing sleeve 2,7 in the insulating sleeve 14. v.

The two units 30 and 30 of the control are grooved cylinders. The unit 30 is connected with the shaft 29 and therefore rotates with the flexible shaft 9. The other unit 30 is connected with the clutch shaft 31; 35 is a pin projecting from the front end of the unit 30', 36, Fig. 4, is a bore in the unit 30 for the reception of the pin 35, and 37 is a ball which is inserted in the bore 36. 32 is a groove in the cylinder 30' which is helical and endless. 32 is a similar, groove in the cylinder 30. 34 is a pin on the control sleeve 33 which engages in the groove 32 of the cylinder 30, and 34 is a pin, also on the control sleeve, which engages in the groove 32 of the cylinder 30'.

The two cylinders are aligned by the pin 35.

41 is a slot in the control sleeve 33 which is adapted to be engaged by a hook 40 at the rear end of the slide 39, as shown in Fig. 2. When the slide is in its normal or forward position, as shown in Fig. 3, a cam 42 on its hook 40 raises on a check in a slot 43 of the handle 4 so that the hook 40 is inactive with respect to the slot 41. The control sleeve 33 is free to rotate with the I shaft 29 which in turn is rotated from the flexible shaft 9 through the clutch 28, 28', and its rotation is transmitted to the cylinder 30 and the shaft 31, the two cylinders being positively connected by the pins 34 and 34. 'Ihisris true for either direction of rotation of the flexible shaft 9.

The clutching means are best seen in Figs. 6 to 9, inclusive. The clutching member 48 is equipped with claws 60 and is keyed on the shaft 31 of the cylinder 30. The mating clutching member 48 is equipped with blocks 61 for engaging in the spaces between the claws 60 of the member 48', as shown in Fig. 7. 'I'he mating clutching member 48 is a sleeve and fitted to slide on a bushing 47 of the clutch shaft 45 which shaft, as mentioned, is connected to the casing 1 by a member 46. This member, which may be a sleeve, is here shown as a fork with its body 64 integral with the free end of the shaft 45 and its arms engaging the casing 1 to which they are connected by rivets 65. The bushing 47 is keyed on the clutch shaft 45 and equipped with serrations 62 engaging in flutes 63 inthe sleeve 48, as best seen in Fig. 7, so that the member 48, the sleeve 47,A the shaft 45 and the casing l rotate in unison but the sliding clutching member 48 is free to.'v slide on the sleeve 47 for throwing in and out the clutch. 49 is a spring on the sliding clutching. mernber 48 which tends to throw in the clutch but is under the control of a bellcrank lever 50, 51.v The bell-crank lever is pivoted on the handle 4 at 52 and engages in a groove 53 on the member 48. 54 is a threaded and adjustable dog in a sleeve 55. near the handle 3 of the shield 2 which is adapted to depress the arm 50 of the bellcrank lever so as to throw out the clutch when the shield 2 is applied to theV casing 1 by depressing the handle 3, as shown in Fig. 2. Normally, that is, when the handle 3 is released as shown in Figs. 1 and 3, the spring 49 throws in the clutch. When the slide 39 is in its forward end position, Fig. 3, the sleeve 33 is free to rotate and rotation is transmitted'to the casing 1 from the flexible shaft 9 by the mechanism described.

When the slide which is preferably knurled at 44 and guided Yin brackets 38, 38' on the handle 4, is pushed to the rear as shown in Fig. 2, the hook 46 engages in the slot 41 of the sleeve 33 by the resiliency of the slide and the sleeve 33 is abruptly arrested. It will appear that the knurled end of' the slide may be engaged by the thumb of the operator so that the slide is advanced and re-I tracted without interrupting the operation of the curler and without releasing the handle 3 if it had been depressed. When the sleeve 33 has been arrested the cylinder 30 continues its rotation with the shaft 29 but its rotation is translated into oscillatory rotative motion of the cylinder 30 by the endless groove 32 in the cylinder 30 into operation with the groove 32 in the cylinder 30. The angle through which the cylinder 30, and consequently the casing 1, is oscillatorily rotated, is a function of the relative lead of the two helical grooves 32, 32'. Interference of the relative motion of the two cylinders is prevented by the ball 37 at the end of the aligning pin 35.

The clutch 48, V48 operates not only as a clutch but also as a safety appliance with a view to preventing damage to the hair. By means of the threaded dog 54 the relative position of the shield 2 and the casing 1 at which the clutch 48, 48 is thrown out, may be varied. The sleeve 55 may be hexagonal as shown, and in this case acts like a nut for holding the dog 54 in position.

Fig. 5 shows a hank 56 of hair engaged between the casing 1 and the shield 2.. The hank is heated very intensely and uniformly by the rotating and heated casing 1 and the steam which forms is immediately discharged through the holes 57 in the shield 2.

In operation the wires 7 and 8 are connected to any suitable system, and rotation is imparted to the flexible shaft 9 which may be helically wound Bowden cable, preferably from a small motor.. In view of the facility of changing from rotation. torocking motion of the casing 1, and in View of the continuous heating of the hank for either motion, the output of my novel curler is much superior to that of any other apparatus for all methods of treating the hair. As mentioned, the hair is rolled when the casing rotates continuously, and subjected to a sort of ironing action when the casing is rocked. In both cases the hair is bent and stretched, in one word,

molded, by the aforesaid treatment. Obviously the intensity of the heat and the speed of the casing 1 may be regulated.

The operation will now be more fully described.

The hair is clamped between the casing 1 and 1 the shield 2 by moving the handles 3 and 4 nearer together manually. The clamping pressure is transformed into resistance against the rotation of the casing 1 by the flexible shaft 9. The resistancereacts on the cylinder 30 so that the 130 cylinder tends to lag with respect to the shaft 9 and the cylinder 30". It is understood that the clutch 48, 48 is thrown in during the rotation, or oscillation, of the casing l. Only when the handles 3 and 4 are moved together beyond a. ,35

parallel to each other and the shield 2 directly 140 engages the casing 1. It is obvious that the relative distance of the handles 3 and 4 must not overstep a certain limit as otherwise the hair would be crushed by the excessive pressure. The moment at which the clutch 48, 48 is thrown out, 1 is determined by adjusting the threaded dog 54. a. Rotation of the casing 1.--The slide 39 is shifted toward the casing 1 and by this movement the hook 40 is moved out of the slot 41 in the sleeve 33., as shown in Fig. 3. is now free to rotate. The flexible shaft 9 which The sleeve 33 150 the'cylinder `30l.and, through Ythe pin 34 and.

thesleeve 33 which is` freeY to rotate yafter the hook has been thrown out, tends to transmit its 'rotationtothe cylinder.30. However, the resistance of..the hair whichfhas been clamped between the casing 1 and vthe shield 2, exerts a braking action on the cylinder 30 so that .the cylinder 30lags while the .cylinder 30 leads. vThe consequence of .the relative rotation of the two cylinders is a slight axial displacement of the sleeve 33 tothe right orrtothe left under the cooperative action of the helical grooves 32 and 32 and thepins .34 and 34.v The sleeve 33 moves to the rightfor a given `direction of-rotation of the shaft 9, and to the left for the oppositel direc-V tion. The axial displacement ofthe sleeve 33 causesfthe end `faces of the cylinders 30,.and,30

to bear on each other, vwhile the ,pin 35 ofthe cylinder 30, bears against theball 37 in the cylinder 30.1. The two cylinders 30 and 30', the sleeve-33 and-the two. pins34 and 34 now rotate as a single unit at the same velocity and in the same direction as the llexible shaft 9.

b. Oscillation of the Casing 1.-The slide39 is in its -nal position at the rear, as shown in Fig. 2. TheY hook 40 engages in the-slot 41 of the sleeve 33, holding the. sleeve 33 against rotation but not interfering with its reciprocation in axial direction. .The vcylinder 30' is still rotated clockwise or anti-'clockwise by the sleeve 9, as the case may be, and by the cooperation of the pin 34 on the sleeve;33 with .the helical groove 32 in the cylinder' 30A the sleeve 33 is reciprocated axially. The groove 32l in thecylinder 30 is endless and therefore the" sleeve 33 performs a complete reciprocation per revolution of the cylinder 30'. The reciprocation ci. the sleeve 33 is transmitted to the cylinder 30 through the pin 34 and the helical groove 32in thecylinder 30. Thisv causes the cylinder 30 to oscillate and in this manner each reciprocation of the vsleeve 33 corresponds to' an v'oscillation of the cylinder 30 and the casing l.

While'the groove 32 in the cylinder 30 must be endlessy in order t'o'transforminto axial displacement ofthe sleeve33 the continuous vrotation of the cylinder` 30. Vwith the flexible shaft 9,

' the casing l is rotated as described under (a), is quite small. Another distinction between the grooves 32 and 32 is that their leads are different for determining the angle through which the casing l is oscillated per revolution of the cylinder 30. The lead of the groove 32 in the cylinder 30 determines the axial displacement of the sleeve 33 while the angle of oscillation of the shaft 31, and the casing l, is the resultant 1. from the axial displacement of the sleeve 33 and the lead of the groove 32 in the cylinder 30.

My novel curler is self-contained, its mechanism being completely enclosed by the handle 4 and the cap 6, without unduly increasing the diameter of the handle 4. The operation of the curler and the regulation of the pressure at which the shield 2 is applied to the hair, are the same as in a normal curler. In View of the rapid rotation of the driving shaft 9 `the hook 40 of the slide 39 attains the slot 41 in the sleeve 33 practically immediately, and the clutch 48, 43 is rthrown in and out as rapidly.

I wish it to` be understood that lI do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.

In the claims ailixed to thisY specification no selection of any particular modicationof the invention is. intended Ato the exclusion or" other modifications thereof and the right to subsequently make claim to any modification not covered by these claims is expressly reserved.
